User:Pavel Dusek/Sandbox/Copyvio Search Chromium Extension
From WikiLectures
An extension for Chromium/Google Chrome web browser that should make copyvio search much easier.
Install the file by clicking to this link: http://www.wikilectures/extensions/ChromeExt/WLCopyvioSearch.crx. Then click on the icon in the upper right corner of the browser, type the title of the page you want to search for, click the run button and then just stare and be amazed. Usage of the standard browser shortcuts to switch tabs (Ctrl+Tab/Ctrl+Shift+Tab) and to close them (Ctrl+w) is recommended.
